Tips and Notes

  • Subscription Required: You need an active ChatGPT Plus or Pro subscription. This provider won't work with free ChatGPT accounts. See OpenAI's ChatGPT plans for more information.
  • Authentication Errors: If you receive a CSRF or other error when completing OAuth authentication, ensure you do not have another application already listening on port 1455. You can check on Linux and Mac by using lsof -i :1455.
  • No API Costs: Usage through this provider counts against your ChatGPT subscription, not separately billed API usage.
  • Sign Out: To disconnect, use the "Sign Out" button in the provider settings.

Limitations

  • You can't use arbitrary OpenAI API models. This provider only exposes the models listed in Kilo Code's Codex model catalog.
  • You can't export/migrate your sign-in state with settings export. OAuth tokens are stored in VS Code SecretStorage, which isn't included in Kilo Code's settings export.
